The authors spent a bit of time studying the tea leaves, and this is what we discovered: officially documented or not, the tags that support element selectors are all block elements, with the exception of the anchor tag (<a>). In other words, the rule of thumb is that, if the tag carries with it a built-in line break, then an element selector will do the trick. The special case is hyperlinks, which we ll cover in detail later in the chapter (hyperlinks are a special case in several ways). For your reference, let s take a quick look at a proof is in the pudding sample file:

panel. Each line of HTML ends in a break tag (<br />), just to keep things visually neat. Every tag is given an element selector that alternates its color between #0000FF (blue) and #00FF00 (green). In normal HTML, most of these lines would display as either blue or green (<img /> contains no actual text, so it wouldn t). In Flash, this holds true only for the block elements. The <a> tag is not a block element, so it does not display an additional, built-in line break as some later tags do. But as the exception to the rule in question, the <a> tag does pick up the blue color (mid-gray, in Figure 13-6) from its element selector. The <body> and <p> (paragraph) tag contents carry their own additional line breaks these are block elements and both display the expected element selector color styling. The <ul> and <li> tags content is combined. These are also block elements and therefore display a combined pair of extra line breaks, as well as the expected element selector styling.
4. Comment out the body and li element selectors in the ActionScript by preceding those lines with
double slashes (//), as shown in Figure 13-7.
5. Test the movie again.
Figure 13-7. Commenting out the <body> and <li> selectors leads to a line-spacing quirk and the concept of inheritance. It should come as no surprise that the <body> tag content is no longer styled. What may raise your eyebrows is that the extra line break is missing. This is a quirk involving only the <body> tag and will raise its head again in the Custom tags section of this chapter. The other thing to notice is that the <ul>/<li> content has changed color. This is because a distinct color style was applied to each tag (green for <ul> and blue for <li>). Blue won the wrestling match earlier because of a CSS concept called inheritance (covered in the Style inheritance section later in the chapter).
6. As a final experiment, uncomment the body element selector by removing the double slashes
from that line. Instead, comment out the p element selector.
7. Test the movie a final time, and you ll see that the <p> content is still blue.
Why Again, this is an example of inheritance, but in a really twisted way. Under normal circumstances, HTML documents feature most of their content inside a <body> tag. If a style is applied to the body, it will trickle down to tags inside that body if those inner tags happen to support the style properties at hand. Here in this Flash file, the <p> content is clearly not inside the <body> content, and yet some phantom inheritance seems to still hold sway. Comment out the body element selector one last time, and the <p> content finally turns black.
8. Close the file without saving the changes.
Every development platform has its quirks, and now you ve seen a few of the ones that belong to Flash. Being aware of these, even if they aren t burned into your neurons, might just save your hide when something about CSS styling surprises you. Now you ve had some experience with block elements and the anchor tag, with the understanding that anchor tags still hold a bit of mystery, yet to be unfolded. Meanwhile, what remains of the other supported HTML tags What s the opposite of a block element, and how can one be styled
